You are making a poster to support your friend for homecoming. Your original photo is 4 inches by 6 inches. You want the photo on the poster to be 5 feet by 7.5 feet. What is the scale factor of this dilation? PLEASE HELP!!!!

Answers

The answer is 9.

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.            

First of all we will convert dimensions of poster from feet to inches.

Now, let us compare sides of our original photo with corresponding sides of poster.

Now, let us compare the second pair of corresponding sides.

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.

An investment earn 6% simple interest. What amount of principal is need to have $3000 after 5 years

Answers

Answer:

The amount of $1000 principal is needed to have $3000 after 5 years.

Step-by-step explanation:

As the interest formula is

[tex]I=Prt[/tex]

Where

P is the principler is the rate in decimalt is the time in years

Substituting the following values in the interest formula and solve for P

I=$3000

r = 6% = 6/100 = [tex]0.06[/tex]

t = 5

so the equation becomes

[tex]I=Prt[/tex]

[tex]3000=P\left(0.06\right)\left(5\right)[/tex]

switch both sides

[tex]P\left(0.06\right)\left(5\right)=3000[/tex]

[tex]P\left(0.3\right)=3000[/tex]

[tex]P=10000[/tex] $

Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.

Step-wise-Step Explanation:

If wall Street intersects 25th Street and 28th Street at right angle then they will Parallel (||) to each other. Because,

If two lines are perpendicular to the third line then those two lines are parallel to each other as they will never meet.

Now Highway 47 is parallel to 28th Street. It means 25th Street is also parallel to Highway 47 because,

If two lines are parallel to the third line then those two lines are parallel to each other as they will never meet.

Alicia received the following seven scores on her math assignments.

80, 90, 10, 75, 90, 95, 99

Find the mean and median. Which measure of center best represents the data?

Answers

Answers:

Mean = 77Median = 90The median is the better measure of center

=============================================

Explanation:

Part (1) Finding the mean

Add up the values to get

80 + 90 + 10 + 75 + 90 + 95 + 99 = 539

Then divide by 7 because there are 7 values in this list

539/7 = 77

The mean is 77

--------------------------

Part (2) Finding the median

First we'll need to sort the values from smallest to largest

{80, 90, 10, 75, 90, 95, 99}

will sort to

{10, 75, 80, 90, 90, 95, 99}

The middle most value is 90 since we have three items below it {10,75,80} and three items above it {90, 95, 99}.

The median is 90

--------------------------

Part (3) Which is the better measure of center?

Nearly all of the values are clustered from 75 to 99. The value 10 is an outlier since it's far from the main cluster. There are more technical processes used to find out if 10 is actually an outlier or not, but we won't deal with that right now.

The much smaller outlier pulls on the mean to make it smaller than what it should be. The mean 77 is too small to represent what the center should be. The median is not affected by outliers, which is why it's used in applications such as home prices.

The median 90 is the better measure of center.

A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below. 2 times 8 + (negative 320) = 336 Which explains whether Brenda is correct? Brenda is correct because her answer represents 336 feet below sea level. Brenda is correct because Negative 16 + (negative 320) = 336. Brenda is not correct because the new position is 2 times 8 + (negative 320) = Negative 304. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336.

what conjecture can you make about the sum of firs 52 positive even numbers​

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. However, the available details is enough to work out a solution.

Considering the first even number: 2

In this case, n = 1

The sum of the first even term is 2.

Represent the sum as a product:

[tex]2 = 1 * 2[/tex]

Considering the first two even numbers: 2 and 4

In this case, n = 2

The sum of the first two even terms is 6

Represent the sum as a product:

[tex]6 = 2 * 3[/tex]

Considering the first three even numbers: 2, 4 and 6

In this case, n = 3

The sum of the first two even terms is 12

Represent the sum as a product:

[tex]12 = 3 * 4[/tex]

Notice the pattern from n = 1 to 3

[tex]2 = 1 * 2[/tex] --- n = 1

[tex]6 = 2 * 3[/tex] --- n = 2

[tex]12 = 3 * 4[/tex] --- n = 3

------------------------------------

It follows that, the sum when represented as a product is: [tex]n * (n + 1)[/tex]

So, the sum of the first 52 even terms would be:

[tex]52 * (52 + 1)[/tex]

Where n = 52

[tex]52 * (52 + 1) = 52 * 53[/tex]

[tex]52 * (52 + 1) = 2756[/tex]

Hence, the sum of the first 52 even terms is 52 * 53 or 2756
